brew doctor
Some "config" scripts were found in your path, but not in system or Homebrew folders.

`./configure` scripts often look for *-config scripts to determine if software packages
are installed, and what additional flags to use when compiling and linking.

Having additional scripts in your path can confuse software installed via Homebrew if
the config script overrides a system or Homebrew provided script of the same name.
